Fast Decision Algorithm for H.264 Based on Statistic and Texture Prediction
Gong Hongyan · Modern Electronics Technique · 2009
To improve H.264 algorithm,based on statistic for the appearance probability of all the modes in the whole sequence,for SKIP mode,a fast decision algorithm,which is to compare the RD cost of SKIP with inter16×16 modes is proposed.For inter8×8,a fast selection algorithm based on texture prediction is proposed.For intra4×4,a simple algorithm is given.the results show that it reduced time by 38% on average while PSNR just reduced nearly 0.05 dB,compared with JM 8.6,thus above method is efficient for H.264 algorithm.
